Well, I've spent the day researching the oil shearing issue with the 6.0 and found some really interesting information. It appears that the fuel injection system likes to shear the oil down from 40 weight to a 30, within 5-7k miles ... doesn't matter if it's synthetic or dino. However, if you use a CJ-4, 10w30 oil, like Rotella T5, there is almost no shear and the oil change interval can be extended. There are a few posts on various sites that discuss oil analysis reports related to these oils. Users are reporting a smoother, quieter engine and some have reported their injector stiction issues have cleared up.
I think I'm going to try the Rotella T5 in my next oil change, when I install the Amsoil bypass. At 5k miles, I'll pull a sample and have it tested. From there, I'll determine if I'll try extending OCI. Everything I've read sounds very promising! |
I use the amsoil setup and run the amsoil, they have a oil made for the extended oil changes. I have 230k on my 04-6.0 and I change the primary filter every 10k and the bypass filter every oil change at 25k, I have benn doing this sinse I had 75k on the truck and have had no issues with bad injectors, my truck has mods and is run in race mode on the Edge juice with att. all the time,better mileage.

Bobfbigman, what oil do you use? What has your oil analysis showed, as far as shearing is concerned?
Everything I've read says the oil shears down to a 30 weight within 5000-7500 miles, regardles if you're using a bypass or not. According to others, who have religiously followed their oil life through oil analysis, the 40 shearing to a 30 affects the chemistry of the oil. That is the reason they began running 10w30. After the same miles traveled, there was little to no change in the viscosity or chemistry of the oil. Based on their research, it has been decided that, for extending oil change intervals, using 10w30 is a much wiser choice. |
I use series 3000 5w-30 for the colder months, the oil they reccomend for extended oil changes and mileage
